Pancake Multicall

Enhanced multicall sdk to safely make multicalls within the gas limit.

Inspired by the 1inch multicall.

Install

``bash
$ pnpm add @pancakeswap/multicall @pancakeswap/sdk viem
`

Usage

$3

By default the calls will be splitted into chunks based on gas limit of each call and the rpc call gas limit of the chain

`typescript
import { ChainId } from '@pancakeswap/chains'
import { multicallByGasLimit, MulticallRequestWithGas } from '@pancakeswap/multicall'

const calls: MulticallRequestWithGas[] = [
{
// Target contract to call
target: '0x',
// Encoded call data
callData: '',
// The maximum gas limit set to this single call
gasLimit: 1_000_000,
},
]

const { results, blockNumber } = await multicallByGasLimit(calls, {
chainId: ChainId.BSC,

// Rpc client. Please refer to PublicClient from viem
client,
})

for (const { success, result, gasUsed } of results) {
if (success) {
// Decode result
decodeResult(result)
}
}
`

$3

The rpc call gas limit can be overriden if provided. Once provided, the multicall sdk won't ask for the gas limit from on chain.

`typescript
const { results, blockNumber } = await multicallByGasLimit(calls, {
chainId: ChainId.BSC,
client,
gasLimit: 150_000_000,
})
`

Other utilities

$3

`typescript
import { ChainId } from '@pancakeswap/chains'
import { getGasLimitOnChain } from '@pancakeswap/multicall'

// Get the rpc call gas limit of the specified chain
const gasLimit = await getGasLimitOnChain(ChainId.BSC)
``
